Controlling Speed Of Disk Patents (Class 386/222)
  • Patent number: 11178402
    Abstract: A method for adjusting a storage bitrate of a data buffer with a buffer size includes: storing data at a selected storage bitrate into the data buffer; writing the stored data from the data buffer into a storage device attached to the data buffer with a predetermined writing speed; monitoring a data amount of the stored data in the data buffer; monitoring a trend of change in the data amount; determining whether the data amount has reached a first ascending threshold, the first ascending threshold being below the buffer size of the data buffer; and in response to the data amount reaching the first ascending threshold and the trend of change in the data amount being an ascending change, reducing the storage bitrate in the data buffer.

  • Patent number: 10910011
    Abstract: A data storage device is disclosed comprising a head actuated over a disk. The disk is spun at a first speed while writing first data to the disk based on a first disk format defining a first capacity for the disk. When a command is received from a host to spin the disk at a second speed different from the first speed, the disk is spun at the second speed while writing second data to the disk based on a second disk format defining a second capacity for the disk different from the first capacity.

  • Patent number: 10073625
    Abstract: The present disclosure relates to a system and methods of controlling a system of storage devices. In particular, the present disclosure relates to methods of controlling peak power and energy consumption in storage systems due to storage devices while maintaining data availability. The system implements a method for maintaining data availability in a storage subsystem by determining a plurality of storage devices to include in a fixed set of storage devices based on a fault tolerance system. The storage devices included in the fixed set are prevented from transitioning between RPM spin modes. The method further involves controlling peak power and energy consumed by the storage subsystem which may include transitioning the storage devices not included in the fixed set from a high RPM operational mode to a low RPM operational mode to reduce peak power and energy consumption.

  • Patent number: 7962001
    Abstract: In conventional technology, when a program which operates in synchronization with reproduction of video and audio instructs a trick play of video and audio such as fast-forward and rewind, the trick play of the video and audio continues even after the program is terminated. This makes it impossible to cancel a redundant trick play which continues for an interval of time which is not expected by the program. In the present invention, a program which instructs a trick play of video and audio is retained, and when the program is terminated, it is determined whether or not the program has instructed the trick play, and if that program has instructed the trick play, the trick play of the video and audio is cancelled. As a result, it is possible to cancel such a redundant trick play which would otherwise continue for some interval of time which is not expected by the program.
